[texhax] Using pages from a PDF document as graphics

[Karl Berry]

     [EPS files] work with most (all?) flavours of TeX.

Arbitrary EPS files are not supported by pdftex, since PDF format is
inherently (and intentionally) limited.

If an EPS is restricted enough, it can be used.  In particular, I read
that the PostScript output by MetaPost can be used in pdftex.  I haven't
tried it myself, and don't know what the general rules are.

Fodder for a nice (short) article regarding all this stuff if you or
anyone is interested :).
